Graft-Tunnel Mismatch in Endoscopic ACL Reconstruction: Reliability of Measuring Tunnel Lengths and Intra-articular Distance.

BACKGROUND: A continued technical challenge for surgeons performing bone-patellar tendon-bone anterior cruciate ligament (ACL) reconstruction with endoscopic techniques is graft-tunnel mismatch. If tibial tunnel and intra-articular distances could be reliably estimated, surgeons could adjust the length of the femoral tunnel to minimize graft-tunnel mismatch. PURPOSE/HYPOTHESIS: To determine whether arthroscopic measurement of the following was reliable: femoral tunnel distance (FTD), tibial tunnel distance (TTD), intra-articular distance (IAD), and total distance (TD; sum of these 3 measurements). It was hypothesized that intraoperative measurement of these distances would be reliable. STUDY DESIGN: Controlled laboratory study. METHODS: Eight sports fellowship-trained orthopedic surgeons independently performed arthroscopic measurements of the FTD, TTD, IAD, and TD in 7 cadaveric knees in which femoral and tibial tunnels had been drilled. Each surgeon performed the measurements twice using an EndoButton depth gauge. Following this, each parameter was measured open with a medial parapatellar approach. Finally, a computed tomography (CT) scan of each knee was performed, with the FTD, TTD, and IAD measured by a musculoskeletal radiologist. Inter- and intrarater reliability of the arthroscopic measurements was calculated, as well as the correlation between arthroscopic measurements and open and CT measurements. RESULTS: Interrater reliability for the arthroscopic measurements was 0.8 for FTD, 0.89 for TTD, 0.61 for IAD, and 0.76 (range, 0.54-0.93) for TD. Intrarater reliability was 0.94 for FTD, 0.97 for TTD, 0.83 for IAD, and 0.93 for TD. The correlation between arthroscopic and open measurements was 0.9 for FTD, 0.94 for TTD, 0.4 for IAD, and 0.84 for TD. The correlation between arthroscopic and CT measurements was 0.85 for FTD, 0.92 for TTD, and 0.71 for IAD. CONCLUSION: The results of this study show that arthroscopic measurement of FTD and TTD has a high degree of intra- and interrater reliability, while that of IAD and TD demonstrates high intrarater reliability but moderate interrater reliability. CLINICAL RELEVANCE: Reliable measurement of the TTD and IAD can potentially allow adjustment of the FTD, minimizing graft-tunnel mismatch in endoscopic ACL reconstruction.

Education of parents in Pavlik harness application for developmental dysplasia of the hip using a validated simulated learning module.

BACKGROUND: The Pavlik harness is the most common initial treatment for developmental dysplasia of the hip worldwide. During treatment, parents are required to re-apply the harness at home. Teaching parents how to apply the harness is therefore paramount to success. While simulated learning for medical training is commonplace, it has not yet been trialed in teaching parents how to apply a Pavlik harness. METHODS: A group of parents underwent a simulated learning module for Pavlik harness application. Parents were evaluated pre- and post-exposure and at one month after testing. A validated objective structured assessment of technical skill (OSATS) and a global rating scale (GRS) specific to Pavlik harness application were used for evaluation. A control group of parents was also tested at both time points. A clinical expert group was used to determine competency. ANOVA and t tests were used to assess differences between groups and over time. RESULTS: Parent scores on the OSATS improved to the level of expert clinicians both immediately post-intervention and at retention testing. However, on the GRS, only half were considered competent due to their inability to achieve the required hip positions. The control group did not improve nor were they considered competent. CONCLUSIONS: The use of a simulated learning module improves both the confidence and skill level of parents in the application of the Pavlik harness. However, the challenges parents face in understanding the more detailed subtleties of medical care suggest that they still require an appropriate level of supervision by clinicians to ensure effective treatment.

Skill Acquisition and Retention Following Simulation-Based Training in Pavlik Harness Application.

BACKGROUND: Simulation-based learning is increasingly prevalent in many surgical training programs, as medical education moves toward competency-based curricula. In orthopaedic surgery, developmental dysplasia of the hip is a commonly treated condition, where the standard of care for patients less than six months of age is an orthotic device such as the Pavlik harness. However, despite widespread use of the Pavlik harness and the potential complications that may arise from inappropriate application, we know of no previously described formal training curriculum for Pavlik harness application. METHODS: We developed a video and model-based simulation learning module for Pavlik harness application. Two novice groups (residents and allied health professionals) were exposed to the module and, at pre-intervention, post-intervention, and retention testing, were evaluated on their ability to apply a Pavlik harness to the model. Evaluations were completed using a previously validated Objective Structured Assessment of Technical Skills (OSATS) and a global rating scale (GRS) specific to Pavlik harness application. A control group that did not undergo the module was also evaluated at two time points to determine if exposure to the Pavlik harness alone would affect skill acquisition. All groups were compared with a group of clinical experts, whose scores were used as a competency benchmark. Statistical analysis of skill acquisition and retention was conducted using t tests and analysis of variance (ANOVA). RESULTS: Exposure to the learning module improved resident and allied health professionals' competency in applying a Pavlik harness (p < 0.05) to the level of the expert clinicians, and this level of competency was retained one month after exposure to the module. Control subjects who were not exposed to the module did not improve, nor did they achieve competency. CONCLUSIONS: The simulation-based learning module was shown to be an effective tool for teaching the application of a Pavlik harness, and learners demonstrated retainable skills post-intervention. This learning module can form the cornerstone of formal teaching of Pavlik harness application for developmental dysplasia of the hip.

Novel Arthroscopic Classification of Osteochondritis Dissecans of the Knee: A Multicenter Reliability Study.

BACKGROUND: Several systems have been proposed for classifying osteochondritis dissecans (OCD) of the knee during surgical evaluation. No single classification includes mutually exclusive categories that capture all of the salient features of stability, chondral fissuring, and fragment detachment. Furthermore, no study has assessed the reliability of these classification systems. PURPOSE: To determine the intra- and interobserver reliability of a novel, comprehensive arthroscopic classification system with mutually exclusive OCD lesion types. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: The Research in OsteoChondritis of the Knee (ROCK) study group developed a classification system for arthroscopic evaluation of OCD of the knee that includes 6 arthroscopic categories-3 immobile types and 3 mobile types. To optimize comprehensibility and applicability, each was developed with a memorable name, a brief description, a line diagram corresponding to the archetypal arthroscopic appearance, and an arthroscopic photograph depicting this archetype. Thirty representative arthroscopic videos were evaluated by 10 orthopaedic surgeon raters, who classified each lesion. After 4 weeks, the raters again classified the OCD lesions depicted in the 30 videos in a new, randomly selected order. Reliability was assessed via the intraclass correlation coefficient (ICC). RESULTS: The interobserver reliability of this novel arthroscopy classification was estimated by an ICC of 0.94 (95% CI, 0.91-0.97) for the first round and 0.95 (95% CI, 0.93-0.98) for the second round. According to the standards for the magnitude of the reliability coefficient of Altman, these ICCs indicate that interobserver reliability was very good. The intraobserver reliability was estimated by an ICC of 0.96 (95% CI, 0.95-0.97), which indicates that the intraobserver reliability was similarly very good. CONCLUSION: The ROCK OCD knee arthroscopy classification system demonstrated excellent intra- and interobserver reliability. In light of this reliability, this classification system may be used clinically and to facilitate future research, including multicenter studies for OCD.

Development and Assessment of a Distal Radial Fracture Model as a Clinical Teaching Tool.

BACKGROUND: Simulation-based learning is increasingly prevalent in the curricula of many surgical training programs. Newly developed simulators must undergo rigorous validity testing before they are used to assess and evaluate surgical trainees. We describe the development of a model that simulates a distal radial fracture requiring closed reduction and cast application and demonstrate its validity. METHODS: We developed a model for simulated treatment of a distal radial fracture with use of a modified Sawbones forearm. Ten junior and ten senior orthopaedic residents were videotaped performing a closed reduction and applying a cast on the model. After each procedure, standard anteroposterior and lateral radiographs of the forearm model were obtained. Two blinded orthopaedic surgeons then rated each resident using a task-specific checklist (Objective Structured Assessment of Technical Skills [OSATS]) and a global rating scale (GRS) as well as radiographic measurements of palmar tilt and three-point index. RESULTS: Compared with the junior residents, senior residents had significantly higher OSATS (p < 0.001) and GRS scores (p < 0.001). The groups did not differ significantly with respect to radiographic palmar tilt (p = 0.86) and three-point index (p = 0.43). All residents were able to restore anatomical alignment, with a mean palmar tilt of 9.1°. In addition, the mean three-point index of all residents was acceptable (0.76). There was a strong correlation between OSATS and GRS scores (r > 0.87; p < 0.01). The inter-rater reliability was high (≥ 0.79) for the OSATS, GRS, and radiographic measurements. CONCLUSIONS: We developed an educational model that simulates a distal radial fracture requiring closed reduction and cast application. We demonstrated construct validity, as the GRS and OSATS tools were able to differentiate senior from junior residents. We were unable to differentiate trainees using radiographic assessment, as all residents restored anatomical alignment and had comparable three-point index scores.

Preoperative Femoral Nerve Block for Hip Arthroscopy: A Randomized, Triple-Masked Controlled Trial.

BACKGROUND: Arthroscopy has become a standard method of treatment for a variety of intra-articular hip disorders. While most arthroscopic hip procedures are performed as outpatient surgeries, patients can still experience significant postoperative pain and opioid-associated side effects. PURPOSE: The potential benefits of a preoperative femoral nerve block (FNB) in hip arthroscopy were explored in a previous retrospective review. The study objective was to confirm these findings in a prospective randomized study. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: Fifty patients undergoing hip arthroscopy were included in this prospective, single-center, randomized controlled trial that was patient-, operator-, and assessor-blinded. Patients received either a preoperative ultrasound-guided FNB with 20 mL of 0.5% bupivacaine (FNB group) or normal saline (control group). Nerve blockade was confirmed via standardized sensory testing before the induction of general anesthesia. The primary endpoint was cumulative consumption of oral morphine equivalent at 24 hours after discharge. Secondary endpoints included opioid use at various time points, pain scores, Quality of Recovery (QoR-27) score, incidence of nausea and vomiting, time to discharge, block-related complications, falls at 24 hours, and patient satisfaction. RESULTS: Fifty patients completed the study, including 27 in the FNB group and 23 in the control group. Most patient characteristics were statistically similar between groups except for operative time, which was longer in the control group. Cumulative oral morphine consumption was lower in the FNB group at 48 hours; there was no difference at 24 hours or 7 days postoperatively. Pain scores were significantly lower up to 6 hours postoperatively in the FNB group compared with control; however, rebound pain was observed at 24 hours after discharge in patients who received FNB. There was no difference in most secondary outcomes. Importantly, a total of 6 patients in the FNB group reported falls (without injury) within the first 24 hours postoperatively compared with none in the control group. Patient satisfaction with pain control was high in both groups at all time points. CONCLUSION: Preoperative FNB may improve early pain control after hip arthroscopy. However, given the observed risk of falls, the routine use of FNB for outpatient hip arthroscopy cannot be recommended.

A Qualitative Investigation of Return to Sport After Arthroscopic Bankart Repair: Beyond Stability.

BACKGROUND: Arthroscopic shoulder stabilization is known to have excellent functional results, but many patients do not return to their preinjury level of sport, with return to play rates reported between 48% and 100% despite good outcome scores. PURPOSE: To understand specific subjective psychosocial factors influencing a patient's decision to return to sport after arthroscopic shoulder stabilization. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Semistructured qualitative interviews were conducted with patients aged 18 to 40 years who had undergone primary arthroscopic shoulder stabilization and had a minimum 2-year follow-up. All patients participated in sport before surgery without any further revision operations or shoulder injuries. Qualitative data analysis was performed in accordance with the Strauss and Corbin theory to derive codes, categories, and themes. Preinjury and current sport participation was defined by type, level of competition, and the Brophy/Marx shoulder activity score. Patient-reported pain and shoulder function were also obtained. RESULTS: A total of 25 patients were interviewed, revealing that fear of reinjury, shifts in priority, mood, social support, and self-motivation were found to greatly influence the decision to return to sport both in patients who had and had not returned to their preinjury level of play. Patients also described fear of sporting incompetence, self-awareness issues, recommendations from physical therapists, and degree of confidence as less common considerations affecting their return to sport. CONCLUSION: In spite of excellent functional outcomes, extrinsic and intrinsic factors such as competing interests, kinesiophobia, age, and internal stressors and motivators can have a major effect on a patient's decision to return to sport after arthroscopic shoulder stabilization. The qualitative methods used in this study provide a unique patient-derived perspective into postoperative recovery and highlight the necessity to recognize and address subjective and psychosocial factors rather than objective functional outcome scores alone as contributing to a patient's decision to return to play.

Taking a Chance or Playing It Safe: Reframing Risk Assessment Within the Surgeon's Comfort Zone.

OBJECTIVES: The purpose of this study was to explore how risk is perceived and experienced by the surgeon and how risk is actively managed in individual practice. BACKGROUND: Risk in surgery has been examined from system-wide and personality perspectives. Although these are important, little is known about the perspective of the individual surgeon. METHODS: A constructivist grounded theory study was conducted to explore surgeons' perspectives on risk in the context of their personal "Comfort Zones." Semistructured, 60-minute interviews were conducted with 18 surgeons who were purposively sampled for sex and subspecialty with a snowballing strategy applied to sample for differences in reputation (conservative vs aggressive). Data were collected and analyzed in an iterative manner until thematic saturation was reached. RESULTS: Surgeons described cases that were inside or outside of their personal comfort zones. When considering cases at the boundary of their comfort zones, participants described a variety of factors that could make them feel more or less comfortable. Specific strategies used to modulate this border were also described. Two perspectives on risk taking became apparent: the procedure-centric perspective described how surgeons viewed their colleagues whereas the surgeon-centric perspective described how surgeons viewed themselves. CONCLUSIONS: A framework for understanding surgeon's unique assessment of risk was elaborated. Increased awareness of the factors and strategies identified in this study can foster critical self-reflection by surgeons of their own risk assessments and those of their colleagues, and provide avenues for more explicit educational strategies for surgical training.

Using a mobile app for monitoring post-operative quality of recovery of patients at home: a feasibility study.

BACKGROUND: Mobile apps are being viewed as a new solution for post-operative monitoring of surgical patients. Mobile phone monitoring of patients in the post-operative period can allow expedited discharge and may allow early detection of complications. OBJECTIVE: The objective of the current study was to assess the feasibility of using a mobile app for the monitoring of post-operative quality of recovery at home following surgery in an ambulatory setting. METHODS: We enrolled 65 consecutive patients (n=33, breast reconstruction surgery; n=32, orthopedic surgery) and asked them to use a mobile phone daily to complete a validated quality of recovery scale (QoR-9) and take photographs of the surgical site for the first 30 days post-op. Surgeons were asked to review patient-entered data on each patient in their roster daily. A semistructured questionnaire was administered to patients and surgeons to assess satisfaction and feasibility of the mobile device. RESULTS: All 65 patients completed the study. The mean number of logins was 23.9 (range 7-30) for the breast patients and 19.3 (range 5-30) for the orthopedic patients. The mean number of logins was higher in the first 14 days compared to the 15-30 days post-op for both breast patients (13.4 vs 10.5; P<.001) and for the orthopedic patients (13.4 vs 6.0; P<.001). The mean score for overall satisfaction with using the mobile device was 3.9 for breast patients and 3.7 for orthopedic patients (scored from 1 (poor) to 4 (excellent)). Surgeons reported on the easy-to-navigate design, the portability to monitor patients outside of hospital, and the ability of the technology to improve time efficiency. CONCLUSIONS: The use of mobile apps for monitoring the quality of recovery in post-operative patients at home was feasible and acceptable to patients and surgeons in the current study. Future large scale studies in varying patient populations are required.

The sizing of hamstring grafts for anterior cruciate reconstruction: intra- and inter-observer reliability.

PURPOSE: The objective of this study was to establish the intra- and inter-observer reliability of hamstring graft measurement using cylindrical sizing tubes. METHODS: Hamstring tendons (gracilis and semitendinosus) were harvested from ten cadavers by a single surgeon and whip stitched together to create ten 4-strand hamstring grafts. Ten sports medicine surgeons and fellows sized each graft independently using either hollow cylindrical sizers or block sizers in 0.5-mm increments­the sizing technique used was applied consistently to each graft. Surgeons moved sequentially from graft to graft and measured each hamstring graft twice. Surgeons were asked to state the measured proximal (femoral) and distal (tibial) diameter of each graft, as well as the diameter of the tibial and femoral tunnels that they would drill if performing an anterior cruciate ligament (ACL) reconstruction using that graft. Reliability was established using intra-class correlation coefficients. RESULTS: Overall, both the inter-observer and intra-observer agreement were >0.9, demonstrating excellent reliability. The inter-observer reliability for drill sizes was also excellent (>0.9). Excellent correlation was seen between cylindrical sizing, and drill sizes (>0.9). CONCLUSIONS: Sizing of hamstring grafts by multiple surgeons demonstrated excellent intra-observer and intra-observer reliability, potentially validating clinical studies exploring ACL reconstruction outcomes by hamstring graft diameter when standard techniques are used. LEVEL OF EVIDENCE: III.

How to assess communication, professionalism, collaboration and the other intrinsic CanMEDS roles in orthopedic residents: use of an objective structured clinical examination (OSCE).

BACKGROUND: Assessing residents' understanding and application of the 6 intrinsic CanMEDS roles (communicator, professional, manager, collaborator, health advocate, scholar) is challenging for postgraduate medical educators. We hypothesized that an objective structured clinical examination (OSCE) designed to assess multiple intrinsic CanMEDS roles would be sufficiently reliable and valid. METHODS: The OSCE comprised 6 10-minute stations, each testing 2 intrinsic roles using case-based scenarios (with or without the use of standardized patients). Residents were evaluated using 5-point scales and an overall performance rating at each station. Concurrent validity was sought by correlation with in-training evaluation reports (ITERs) from the last 12 months and an ordinal ranking created by program directors (PDs). RESULTS: Twenty-five residents from postgraduate years (PGY) 0, 3 and 5 participated. The interstation reliability for total test scores (percent) was 0.87, while reliability for each of the communicator, collaborator, manager and professional roles was greater than 0.8. Total test scores, individual station scores and individual CanMEDS role scores all showed a significant effect by PGY level. Analysis of the PD rankings of intrinsic roles demonstrated a high correlation with the OSCE role scores. A correlation was seen between ITER and OSCE for the communicator role, while the ITER medical expert and total scores highly correlated with the communicator, manager and professional OSCE scores. CONCLUSION: An OSCE designed to assess the intrinsic CanMEDS roles was sufficiently valid and reliable for regular use in an orthopedic residency program.

CONTEXTE: Évaluer la compréhension et l'application des 6 rôles intrinsèques CanMEDS (communicateur, professionnel, gestionnaire, collaborateur, promoteur de la santé, érudit) chez les résidents pose un défi pour les responsables de la formation médicale postdoctorale. Nous avons émis l'hypothèse selon laquelle un examen clinique objectif structuré (ECOS) conçu pour évaluer plusieurs rôles CanMEDS intrinsèques serait suffisamment fiable et valide. MÉTHODES: L'ECOS comportait 6 stations de 10 minutes, permettant chacune d'évaluer 2 rôles intrinsèques à l'aide de scénarios basés sur des cas (avec ou sans recours à des patients standardisés). Les résidents ont été notés au moyen d'échelles en 5 points et d'une évaluation globale de leur rendement à chacune des stations. La validité convergente a été vérifiée par corrélation avec les rapports d'évaluation en cours de formation (RÉF) des 12 mois précédents et un classement chiffré créé par les directeurs du programme (DP). RÉSULTATS: Vingt-cinq résidents des années 0, 3 et 5 y ont participé. La fiabilité interstation pour les scores totaux aux tests (en pourcentage) a été de 0,87, tandis que la fiabilité pour chacun des rôles de communicateur, collaborateur, gestionnaire et professionnel, a été supérieure à 0,8. Les scores totaux aux tests, les scores aux stations individuelles et les scores pour les rôles CanMEDS individuels ont tous fait état d'un effet significatif selon le niveau des résidents. L'analyse des classements établis par les DP quant aux rôles intrinsèques a révélé une forte corrélation avec les scores au test ECOS pour les rôles. On a observé une corrélation entre les RÉF et l'ECOS pour le rôle de communicateur, tandis que les RÉF pour le rôle d'expert médical et les scores totaux ont été en forte corrélation avec les scores de l'ECOS pour les rôles de communicateur, de gestionnaire et de professionnel. CONCLUSION: Un ECOS conçu pour évaluer les rôles CanMEDS intrinsèques s'est révélé suffisamment valide et fiable pour un usage régulier dans un programme de résidence en orthopédie.

Development of a cast application simulator and evaluation of objective measures of performance.

BACKGROUND: Surgical simulation offers a low-risk learning environment with repetitive practice opportunities for orthopaedic residents. It is increasingly prevalent in many training programs, as acquisition of technical skills in the face of educational demands and reduced work hours becomes more challenging. In addition to surgical skills, orthopaedic residents must also learn the technique of cast application. Deficiencies in casting skill are risk factors for re-displacement of fractures and cast-specific complications. Formal educational models to instruct or to evaluate casting technique have not been well described or tested. The purposes of this study were to develop a cast application simulator and to validate a novel method of evaluating casting skill. METHODS: A module that simulates short arm cast application on a synthetic forearm model was developed. An Objective Structured Assessment of Technical Skill checklist was created with use of Delphi methodology involving nine content experts (five orthopaedic surgeons and four orthopaedic technologists). Nine participants (three medical students, three orthopaedic residents, two orthopaedic fellows, and one orthopaedic technologist) were used to evaluate the reliability and validity of the checklist. Nine de-identified videos of cast application were recorded and were utilized to test the newly developed Objective Structured Assessment of Technical Skill checklist and Modified Global Rating Scale for reliability and validity. Participants were grouped by training level (medical students, orthopaedic residents, and orthopaedic fellows or orthopaedic technologists) and were evaluated twice. RESULTS: Reliability was high as shown by intraclass correlation. The inter-rater reliability was 0.85 for the Objective Structured Assessment of Technical Skill, 0.81 for the Modified Global Rating Scale performance, and 0.78 for the Modified Global Rating Scale final product; the intra-rater reliability was 0.88 for the Objective Structured Assessment of Technical Skill, 0.85 for the Modified Global Rating Scale performance, and 0.81 for the Modified Global Rating Scale final product. The Objective Structured Assessment of Technical Skill checklist scores were 9.28 points for the medical students, 17.46 points for the orthopaedic residents, and 18.85 points for the orthopaedic fellows or orthopaedic technologists (p < 0.05, F = 6.32). The Modified Global Rating Scale performance and final product scores also reflected the level of training. Post hoc analysis showed a significant difference between the medical students and orthopaedic fellows or orthopaedic technologists for the Objective Structured Assessment of Technical Skill checklist and Modified Global Rating Scale. CONCLUSIONS: This casting simulation model and evaluation instrument is a reliable assessment of casting skill in applying a short arm cast. However, given the inability to stratify all three groups on the basis of the level of training, further work is needed to establish construct validity.

Drilling techniques for osteochondritis dissecans.

Although the advanced stages of osteochondritis dissecans remain challenging to treat, most early-stage lesions in skeletally immature patients, if managed appropriately, can be stimulated to heal. For stable lesions that do not demonstrate adequate healing with nonoperative measures, such as activity modification, weight-bearing protection, or bracing, drilling of the subchondral bone has emerged as the gold standard of management. Several techniques of drilling exist, including transarticular drilling, retroarticular drilling, and notch drilling. Although each technique has been shown to be effective in small retrospective studies, higher-powered prospective comparative studies are needed to better elucidate their relative advantages and disadvantages.

A qualitative investigation of the decision to return to sport after anterior cruciate ligament reconstruction: to play or not to play.

BACKGROUND: Primary anterior cruciate ligament (ACL) reconstruction is known to have excellent outcomes, but many patients do not return to their preinjury level of sport participation. Previous studies have used subjective outcome scores to evaluate this discrepancy, but none to date has used qualitative, in-depth patient interviews. PURPOSE: To understand the factors influencing a patient's decision to return to his or her preinjury level of sport after ACL reconstruction. HYPOTHESIS: Extrinsic and intrinsic factors may affect one's decision to return to sport after primary ACL reconstruction despite good functional knee scores. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: An experienced interviewer conducted qualitative, semistructured interviews of 31 patients, aged 18 to 40 years, who had undergone primary ACL reconstruction surgery. All participated in sport before injury and had a minimum 2-year follow-up with no further surgeries or knee injuries. Qualitative analysis was then performed to derive codes, categories, and themes. An assessment of preinjury and current sport participation by type, level of competition, and Marx activity score, along with patient-reported knee function, was also conducted. RESULTS: Patient interviews revealed 3 overarching themes: fear, lifestyle changes, and innate personality traits. Elements of these factors were shown to largely influence the decision to return to the preinjury sport both in those patients who had returned and those who had not returned to sport. Less common factors included the surgeon's advice not to return, depressed mood, and persistent knee pain. CONCLUSION: Patients who did not return to their preinjury level of sport after primary ACL reconstruction despite having good knee function were largely influenced by fear, shifts in priority, and individual personalities. This study highlights the importance for treating physicians to recognize and address psychological factors and lifestyle changes that largely contribute to a patient's postoperative decision to return to sport. Results from this study will allow surgeons and health care professionals to educate patients contemplating surgery and to better understand the recovery process not only from sport-related surgeries but other surgical interventions with the goal of returning to activity.

Juvenile Osteochondritis Dissecans in a 13-year-old male athlete: A case report.

OBJECTIVE: To present the clinical management of juvenile osteochondritis dissecans (OCD) of the knee and highlight the importance of a timely diagnosis to optimize the time needed for less invasive, non-operative therapy. CLINICAL FEATURES: A 13-year-old provincial level male soccer player presenting with recurrent anterior knee pain despite ongoing manual therapy. INTERVENTION AND OUTCOME: A multidisciplinary, non-operative treatment approach was utilized to promote natural healing of the osteochondral lesion. The plan of management consisted of patient education, activity modification, manual therapy, passive modalities and rehabilitation, while being overseen by an orthopaedic surgeon. CONCLUSIONS: Considering the serious consequences of misdiagnosing osteochondritis dissecans, such as the potential for future joint instability and accelerated joint degeneration, a high degree of suspicion should be considered with young individuals presenting with nonspecific, recurrent knee pain. A narrative review of the literature is provided to allow practitioners to apply current best practices to appropriately manage juvenile OCD and become more cognizant of the common knee differential diagnoses in the young athletic population.

OBJECTIF: Présenter le traitement clinique de l'ostéochondrite disséquante juvénile (OCD) du genou et souligner l'importance d'un diagnostic précoce en vue d'optimiser le temps nécessaire pour un traitement non chirurgical moins invasif. CARACTÉRISTIQUES CLINIQUES: Un joueur de soccer de 13 ans, au niveau provincial, présente des douleurs antérieures du genou (récurrentes) malgré un programme de thérapie manuelle en cours. INTERVENTION ET RÉSULTATS: Une approche de traitement multidisciplinaire non chirurgical a été utilisée pour favoriser la guérison naturelle de la lésion ostéochondrale. Le plan de traitement comportait la sensibilisation du patient, la modification des activités, la thérapie manuelle, les modalités passives et la réadaptation, sous la supervision d'un chirurgien orthopédiste. CONCLUSIONS: Compte tenu des conséquences graves d'un mauvais diagnostic de l'ostéochondrite disséquante, telles que la possibilité d'une instabilité articulaire et d'une dégénérescence accélérée des articulations à l'avenir, il faut être extrêmement suspicieux avec les jeunes qui présentent des douleurs récurrentes non spécifiques du genou. Un examen narratif des revues scientifiques est offert pour permettre aux professionnels d'avoir recours aux pratiques exemplaires actuelles pour traiter adéquatement l'OCD juvénile et de se sensibiliser davantage aux diagnostics différentiels communs du genou chez les jeunes sportifs.

Remembering our roots: eponyms in sports medicine.

For as long as athletes have been competing, injuries from competition have resulted. Sports medicine has a rich and storied history with significant contributors from many different countries and civilizations. Over time, we have honored the contributions of important figures in sports medicine with the use of eponyms. However, the continued use of eponyms in medicine has been called into question by a number of authors. They cite inaccuracies in definition and context, lack of descriptive value, and the possible celebration of unsavory characters. However, eponyms are pervasive in the medical literature. They bring color and character and allow us to honor those who came before us. Furthermore, eponyms can hide some distressing aspects of a disease. This review of eponyms in sports medicine provides an opportunity to celebrate our predecessors, recognize the international flavor of sports medicine, and promote accurate use of eponyms for the future.

Drilling juvenile osteochondritis dissecans: retro- or transarticular?

BACKGROUND: Early diagnosis and successful treatment of juvenile osteochondritis dissecans (JOCD) is essential in preventing articular degeneration at a young age. Surgical treatment of stable JOCD lesions failing nonoperative treatment involves retroarticular or transarticular drilling to induce revascularization and healing. Multiple case series report high healing rates and infrequent complications for both retroarticular and transarticular drilling modalities; however, it is unclear from these individual reports whether one mode of drilling provides higher healing rates. QUESTIONS/PURPOSES: We asked whether transarticular or retroarticular drilling of stable JOCD lesions results in differing patient-oriented outcomes, rates of radiographic healing, time to radiographic healing, and complication rates. METHODS: We systematically reviewed the short-term clinical outcomes of retroarticular and transarticular drilling of stable OCD lesions. PubMed and additional sources identified 65 studies; 12 studies met inclusion criteria. RESULTS: Heterogeneity and quality of studies limited review to qualitative analysis. No clear differences were seen in patient-oriented outcomes after treatment with either drilling modality. Radiographic healing for JOCD lesions drilled retroarticularly occurred in 96 of 111 (86%) lesions in an average of 5.6 months. Transarticular drilling of JOCD lesions resulted in 86 of 94 (91%) lesions healing by radiography in an average of 4.5 months. No complications were reported for either drilling modality. CONCLUSIONS: Retroarticular and transarticular drilling of stable lesions results in comparable short-term patient-oriented outcomes and radiographic healing. Further high-quality comparative studies are required to adequately compare drilling modalities, clearly define radiographic healing, and patient-oriented outcomes after nonoperative treatment.

Waking up the next morning: surgeons' emotional reactions to adverse events.

CONTEXT: The adverse patient event is an inherent component of surgical practice, but many surgeons are unprepared for the profound emotional responses these events can evoke. This study explored surgeons' reactions to adverse events and their impact on subsequent judgement and decision making. METHODS: Using a constructivist grounded theory approach, we conducted 20 semi-structured, 60-minute interviews with surgeons across subspecialties, experience levels, and sexes to explore surgeons' recollections of reactions to adverse events. Further interviews were conducted with six general surgeons to explore more immediate reactions after 28 adverse events. Data coding was both inductive, developing a new framework based on emergent themes, and deductive, using an existing framework for care providers' reactions to adverse events. RESULTS: Surgeons expressed feeling unique and alone in the depths of their reactions to adverse events and consistently described four phases of response, each containing cognitive and emotive components, following such events. The initial phase (the kick) involved feelings of failure ('Am I good enough?') experienced with a significant physiological response. This was shortly followed by a second phase (the fall), during which the surgeon experienced a sense of chaos and assessed the extent of his or her contribution to the event ('Was it my fault?'). During the third phase (the recovery), the surgeon reflected on the adverse event ('What can I learn?') and experienced a sense of 'moving on'. In the fourth phase (the long-term impact), the surgeon experienced the prolonged and cumulative effects of these reactions on his or her own personal and professional identities. Surgeons also described an effect on their clinical judgement, both for the case in question (minimisation) and future cases (overcompensation). CONCLUSIONS: Surgeons progress through a series of four phases following adverse events that are potentially caused by or directly linked to surgeon error. The framework provided by this study has implications for teaching, surgeon wellness and surgeon error.

Percutaneous curettage and suction for pediatric extremity aneurysmal bone cysts: is it adequate?

BACKGROUND: The purpose of our study was to evaluate the effectiveness of treating extremity aneurysmal bone cysts (ABC) by percutaneous curettage compared with open intralesional excision. METHODS: A retrospective review of 17 patients with histologically proven primary ABCs and no evidence of a secondary lesion treated either by percutaneous curettage or open intralesional excision with at least 24-month follow-up was undertaken. The percutaneous curettage group was uniformly treated on an outpatient basis using angled curettes under image guidance followed by intralesional evacuation. The primary outcome was radiographic healing using the Neer/Cole 4-grade classification. Complications were noted. RESULTS: Seventeen patients with a mean age of 11.7 years (range, 1.7 to 17.5) were evaluated. Nine patients underwent percutaneous curettage and 8 had an open intralesional excision. The 2 treatment groups were comparable with regard to age, sex, number of procedures, morphologic type of ABC, and follow-up period. At follow-up, the proportion of patients with satisfactory healing (Neer/Cole grades I and II) were similar among the 2 groups (P = 0.74). In the percutaneous curettage group, 2 cases recurred necessitating repeat procedures, whereas 1 case recurred in the open intralesional excision group and was successfully treated percutaneously. CONCLUSIONS: Percutaneous curettage is a safe and minimally invasive alternative for extremity ABCs that can be performed as an outpatient procedure. Not all ABCs require wide exposure and an open intralesional excision. LEVEL OF EVIDENCE: III.
